[Bug][cyber] Safety filter blocked routine dev work on drone RSA auth plugin after model switch (req_011CcnWhgbceAtzYUrYPwG71)

Triage: kind cyber · domain general · flagging model Opus 4.8 (1M context) · severity session-halted (blocked authorized work) · reproducible: yes — server-side via the Request ID(s) below

Type: Cybersecurity safety-filter false positive · Work domain (heuristic): general

Why this is a false positive

The session was implementing an RSA-based authentication plugin for a drone communication protocol (key loading, auth frame generation, gitignore verification for key material) — standard protocol-implementation work, not an attack tool. Switching the active model to a 1M-context variant mid-session triggered a cybersecurity-topic safeguard on a routine "keep working on the project" continuation message, with no new sensitive content introduced. This appears to be a false positive tied to the model switch context rather than the actual message content, and it halted an otherwise legitimate, in-scope engineering session.

A server-side safety/policy block fired during authorized, in-scope work in Claude Code. Filing as a false positive. Recurred 1× across 1 session(s); first seen 2026-07-07T10:08:21.078Z.
